Back to Fascinating Experiments
Materials
- 2 x 2L pop bottles (empty)
- Water
- Food colouring
- Glitter, beads or other small decorative items (optional)
- Masking or duct tape (optional: purchase a bottle connector from an educational supply store)
Procedure
- Fill one of the pop bottles, leaving a few inches of space at the top.
- Put a few drops of food colouring into the bottle.
- Add any glitter, beads or other small decorative items.
- Connect the two bottles at their necks, using masking or duct tape, or a purchased bottle connector.
- Turn the attached bottles over, while gently rotating the entire assembly. Observe and record what happens!

Suggestions for Art Activities
Have students draw pictures of their own tornado-in-a-bottle. Make it a multimedia project by having them glue glitter, beads, sequins and other small items to the picture.
Print colour-copies of our tornado-in-a-bottle and experiment with collage techniques. Give students photographs of themselves, so that they can really get “into” the picture!
Have students observe their tornado-in-a-bottle and write down the words that come to mind (e.g., rushing, swirling, etc.), then have them write a poem inspired by their science.
What else could your class do with a tornado-in-a-bottle? We can’t wait to see what they come up with!
